Behçet's disease (BD) is a multisystemic disorder of unknown etiology mainly defined by recurrent oral aphthosis, genital ulcers, and chronic relapsing bilateral uveitis, all of which represent the "stigmata" of disease. However, many other organs including the vascular, neurological, musculoskeletal, and gastrointestinal systems can be affected. The gastrointestinal involvement in Behçet's disease (GIBD), along with the neurological and vascular ones, represents the most feared clinical manifestation of BD and shares many symptoms with inflammatory bowel diseases, such as Crohn's disease and ulcerative colitis...

Karl Schenck, Olav Schreurs, Katsuhiko Hayashi, Kristen Helgeland
Nerve growth factor (NGF) and its different precursor forms are secreted into human saliva by salivary glands and are also produced by an array of cells in the tissues of the oral cavity. The major forms of NGF in human saliva are forms of pro-nerve growth factor (pro-NGF) and not mature NGF. The NGF receptors tropomyosin-related kinase A (TrkA) and p75 neurotrophin receptor (p75(NTR)) are widely expressed on cells in the soft tissues of the human oral cavity, including keratinocytes, endothelial cells, fibroblasts and leukocytes, and in ductal and acinar cells of all types of salivary glands...

Chronic ulcerative stomatitis is an immune-mediated mucocutaneous disorder characterized clinically by erosions or ulcers. Most cases are limited to the mouth. The histopathological features are non-specific or mimic those of oral lichen planus, and studies by immunoflorescent microscopy are essential for definitive diagnosis. The defining immunopathogenic mechanism is the binding of IgG to the nuclear protein deltaNp63alpha of keratinocytes in the basal and parabasal cell layers of the oral stratified epithelium...

A 49-year-old woman presented with a superficial, ulcerative laesion of approximately 7x3 mm of the marginal labial gingiva of the first upper incisor right. The laesion had returned twice after limited surgical excision. On the basis of a new, extensive excisional biopsy, additional investigation was carried out by the pathologist, which led to a diagnosis of localised (juvenile) spongiotic gingival hyperplasia (LJSGH). The aetiology of LJSGH is still unclear. A typical characteristic is the localised and solitary presence of the laesion...

BACKGROUND: Recurrent aphthous stomatitis (RAS) is one of the most common chronic oral diseases with morbidity ranging from 5% to 20%. The pathogenesis is still not fully understood though immune dysregulation and local trauma have been implicated and the curative effect that can be achieved through current therapy is mainly to alleviate the pain. So, the understanding of its molecular mechanisms can allow the prevention and treatment of RAS at the molecular level. METHODS: 14 normal tissues and 14 ulcerated tissues were subjected to Affymetrix Human Genome U133 Plus 2...
